Information on InstallationMicrosoft has released a PPTP Performance Update for the Windows NT Workstation and Server version 4.0. We have made refinements to current Windows PPTP client and server communication technologies that significantly improve the performance of secure PPTP connections via the Internet.This update should be applied to both Windows NT 4.0 Servers and Workstations. You must have Service Pack 3 for Windows NT 4.0 installed before applying this update. Windows NT 4.0 Servers running Routing and Remote Access Service (RRAS) must first apply this Windows NT PPTP Update followed by the RRAS Hotfix 2.0. For more information, please see the following article in the Microsoft Knowledge Base: ARTICLE-ID: Q168469This update is packaged in an auto-install format. Copy the Update to a temporary directory, and double-click the executable name or type the executable name "pptpfixi.exe" for x86 or "pptpfixa.exe" for alpha (without quotation marks) at a command prompt to install. The files can also be extracted from the Update without installing them. To do this, copy the Update to a temporary directory, and type pptpfixi/x or pptpfixa/x at a command prompt. After extracting the files, the Update can be installed by typing hotfix at a command prompt. To uninstall this update, type HOTFIX -Y from the directory you copied the files to. Output of "HOTFIX -?":
RAS Servers that terminate compulsory PPTP connections from an FEP (Front End Processor) must disable historyless compression/encryption in order for legacy Windows 95 clients to receive data properly. An FEP is a dial-up server which can create a PPTP tunnel on behalf of its dial-up clients. This feature is available from several Access Server vendors, including Compaq (Microcom), Ascend, and 3com. The value to set in the registry to enable/disable historyless encryption/compression is: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NdisWan \Parameters
